Managing the context window is crucial for AI applications, as exceeding its limits can lead to a silent degradation of performance rather than an error. While context windows have expanded significantly, the usable portion is often much smaller due to factors like "lost in the middle" attention degradation and the linear cost of input tokens. Developers can employ strategies such as sliding windows with summarization, selective retrieval of relevant past messages, token-aware prompt design with fixed budgets, and external memory systems to maintain performance and predictability in long conversations.
